Flies with inner ears?

Animal Communication: Flies' Ears Are Tuned In

Male fruit flies sing to females with quiet, close-range wing vibrations. A new study has found that the flies' antennal ears show active tuning to the species-specific frequencies of songs.

Listening with Two Ears

Post-treatment effects of local GDNF administration to the inner ears of deafened guinea pigs.

For patients with profound hearing loss, a cochlear implant is the only treatment available today. The function of a cochlear implant depends in part on the function and survival of spiral ganglion neurons. Following deafferentation, glial cell-derived neurotrophic factor (GDNF) is known to affect spiral ganglion neuron survival. The purpose of this study was to assess delayed GDNF treatment af...

Potential of Pluripotent Stem Cells for the Replacement of Inner Ears

The inner ear, which manages our senses of hearing and balance, has mechanosensitive hair cells, which convert vibration into electronic signal to depolarize auditory or vestibular neurons. Inner ear functions depend largely on hair cells, their associated neurons and cochlear lateral wall, and defects in these cells result in hearing loss and deafness. Although some investigations indicated ha...

Magnetic Injection of Nanoparticles Into Rat Inner Ears at a Human Head Working Distance

Due to the physics of magnetic fields and forces, any single magnet will always attract or pull-in magnetically-responsive particles. However, there are a variety of clinical needs where it is advantageous to be able to push away or ‘magnetically inject’ therapeutic particles. Here we focus on magnetic injection to treat inner-ear diseases. The inner ear is behind the blood-ear barrier, meaning...
